“…It involves the absorption of photons having energy (hν) equal to or greater than the band gap energy (E g ) of a semiconductor material, then there is generation of electron hole pairs. 7,8 Upon the incident of light on semiconductor, electrons (e -) jump from its valence band (VB) to conduction band (CB), thus there is concurrently formation of a hole (h + ) in the valence band (Eq. (1)).…”

Intensive research work has been carried out for the degradation of organic pollutants present in the environment using the metal oxide semiconductors. For the same, TiO 2 , ZnO semiconductor photocatalysts has been widely used, but the main drawback of these materials is able to utilize the UV spectrum only, due to its high band gap property. Since solar spectrum contain a significant proportion of the visible light, it is imperative that for an active and versatile utilization of the incident solar energy. The visible light active photocatalysts with a relatively smaller band gap are developed. However, smaller band gap often results in rapid recombination and conversion of photonic energy into non-usable heat. The main aim of this review is provide different ways for utilization of solar spectrum using different catalyst with relatively smaller band gap.

The Ti 4 O 7 modified Ti/PbO 2 electrodes have been prepared by electrodeposition, and investigated systemically using scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDS), powder X-ray diffraction (XRD), photoluminescence spectroscopy (PL), and degradation of anthraquinone dye (reactive brilliant blue KNÀR: C 22 H 16 N 2 Na 2 O 11 S 3 ). It is found that the Ti 4 O 7 modified Ti/PbO 2 electrodes possessed smaller PbO 2 crystal grains, good porous structure, enhanced oxygen evolution over-potential and higher electrical conductivity, as compared to that of Ti/PbO 2 electrode. Additionally, the Ti 4 O 7 modified Ti/PbO 2 electrode exhibited also longer accelerated lifetime, and higher photoelectrocatalytic activity for degradation of anthraquinone dye (reactive brilliant blue KNÀR) than that of Ti/PbO 2 electrode. The enhancement of the decolorization efficiency and stability for Ti 4 O 7 modified Ti/PbO 2 electrodes can be ascribed to the large electrochemical active areas, the presence of photoelectric synergism, rapid separation of photogenerated carriers, inhibition of oxygen precipitation, high current efficiency for formation of hydroxyl radicals, and the weakening of internal stress in PbO 2 coatings.
